LE GRAND KNIFFEN, OF CHICAGO, ILLINOIS.

STOCK-FEED MACHINE.

SPECIFICATION forming part of Letters Patent No. 593,380, dated November 9, 1897.

Application filed August 26, 1896.

To all whom it may concern.-

Be it known that I, LE GRAND KNIFFEN, a citizen of the United States of America, resid ing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stock-Feed Machines, of which the following is a specification.

My invention relates to certain improvements in stock-feed machines, the object being to connect a feed-cutter and feed-grinding machine in such a manner that both will be supported by one main framework and driven by a single drive wheel an d shaft, thus doing away with the necessity of using two separate shafts and driving-pulleys, as in independent machines of this class.

To such end the invention consists in certain novel features of construction, which will be fully described in the specification and particularly pointed out in the claims.

In the drawings presented herewith, Figure l is an end view of a feed-cutter and feedgrinder connected by my improved connecting devices. Fig. 2 is a view thereof, partly in plan and partly in horizontal section, the section being taken through the line 2 2, Fig. 1. Fig. 8 is a perspective view of a bracket used in connection with my invention. Fig. 4C is a perspective View of the bracket, showing also the means for vibrating the feedchute used in the feed-grinder. Fig. 5 is a detail section of a grinding-bur used in the feed-grinder and showing the means for connecting the bur with the main driving-shaft of the feed-cutter. Fig. 6 is a detail crosssection through the line 6 6, Fig. 5. Fig. 7 is a similar view through the line 7 7, Fig. 5. Fig. 8 is a detail front View of one of the standards which supports thehopper of the feed-grinder. Fig. 9 is a central longitudinal section through the'line 9 9, Fig. 10; and Fig. 10 is a horizontal section through the line 10 10, Fig. 9.

In order to properly illustrate my invention, I have shown a feed-cutter of that class in which the stock is continuously fed into the same from one end and cut into small particles such as will be desirable for feed for cattle. A feed-grinder is also shown in the drawings which is adapted to grind kernels of corn, oats, &c.,into very small parti Serial No- 603,956. (No model.)

cles. These two machines taken separately are of known forms, but are the most suitable for my purpose.

In Figs. 1, 9, and 10, A A A represent two vertical members and the base, respectively, of the framework of a feed-cutter, and A the spout or chute through which the cut feed is discharged. 13 represents the concave in which rotatable cutters B are arranged, these cutters being adapted'to cut the stock into small particles and receiving their rotating motion from a shaft C, upon which is mounted a wheel 0, which may either be used as a flywheel or belt-wheel, as may be desired. In

this class of feed-cutters the other operating portions of the machine are driven by gear-.

ing the same to the shaft 0, and I have shown a gear-wheel upon this shaft which may evidently rotate the other gears, thus imparting the motion to the other operating portions of the feed-cutter. I

To the framework of the feed-cutter are secured two beams A A one arranged above the other and extending laterally from the machine, the ends of these beams being con nected by two vertical beams A A thus making a perfectly-rigid framework capable of sustaining a considerable weight. The object of this framework is to support two gear-wheels, one of which is seen at 0 (see Fig. 2,) secured upon a shaft 0, the other gear being in mesh with the gear 0 arranged above the same and fast upon a shaft 0, extending into the'feed-cutten- The shafts c c are adapted to carry feed-rollers which feed the stock into the machine.

The grinder is seen in Figs. 1 and 2, and comprises, with other elements, a hopper D, in which grain-such as corn, oats, &c.may be placed,and a vibrating feed-chute d,located immediately below the spout of the hopper D and vibrated by. means of a device hereinafter described, this vibrating chute being adapted'to discharge the grain into the grind ing-mill proper, E, which is provided with two grinding-disks e e, of ordinary construction, such as are used in grinding-mills of this-class. A discharge-spout E is formed upon the lower portion of the grinding-mill and is adapted to deliver the ground feed into suitable receptacles provided therefor.

The feed cutter and grinder thus far de- IOO scribed are of the most suitable kind upon which to apply my improved connecting devices and have been described very briefly for the reason that they are of well-known forms, and therefore it is not thought necessary to explain them in detail. I will now proceed to describe the devices used to connect these machines.

Fig. 3 represents a bracket which is used to connect the frames of the two machines and which consists of a yoke-shaped portion F and two laterally-extending ears f f. The bracket F is secured to the upright A by means of bolts f passing through the ears ff, and a diagonal brace F is provided to support one end of the bracket. As seen in Figs. 1 and 2, the brace F extends diagonally from the bracket to one of the upright members A of the feed-cutter frame and is secured thereto by means of the bolt a, which is ordinarily used to connect the upright members A A. The hopper D is supported by two standards D D, the lower ends of which are bifurcated and formed into two flanges cl (2, upon which rests the head of a bolt (1 (1 which passes through holes in the bracket provided therefor, as seen at f Fig. 3. One of the bolts d besides securing the standards D D to the bracket, passes through one end of the brace F, thereby securing it to the under side of the bracket,

The grinding-mill proper,E,is provided with a pair of radially-extending lugs e 6 and these lugs rest upon the extreme ends of the.

bracket, the same being provided with holes through which bolts pass to secure the mill in the proper place upon the bracket and in its proper relation to the other portions of the feed-grinder. The drive-shaft O of the cutter extends beyond the same and is concentric with the grinding-disks of the feedgrinder. The bur e of the mill is stationary and is held in place by the casing of the mill, but the bur e is rotatable and receives such motion from the shaft 0 of the feed-cutter. To connect the shaft 0 with the grinding-bur e, a thimble gis slipped upon the end of the shaft C, said shaft bein' g provided with a keyseat 0 and a feather g being formed upon the thimble and adapted to be seated in the key-seat 0 thereby securing the thimble upon the shaft, so as to be rotatable therewith, but still to have a slight longitudinal motion thereon. As seen in Fig. 7, the end of the thimble is formed with two parallel faces, and upon these faces are formed two lugs g 9 resting against corresponding lugs 9 formed upon the face of the grindingbur e, and, as shown, this bur is formed with a concave face g, in the center of which is a socket 9 in which rests the convex end 9 of the thimble. This convex and concave connection between the grinding-bur and the thimble is for the purpose of centering the disk, so that it will rotate in the proper manner. The shaft is journaled near its end in a bearing 9 which is bolted to the bracket,

as seen in Fig. 2, and adjacent to the bearing-block g an eccentric h is secured to the shaft C, this eccentric being adapted to oscillate a U-shaped arm H of a bell-crank lever, the arms H of which extend upward and are connected by 'a transverse member 72,, hinged to the bottom of the vibrating chute d. The

bell-crank oscillating lever H H is pivoted upon lugs 7L2 upon the standards D D, and a yoke-shaped support 11 is pivoted upon lugs 7L3, also formed upon the standards D D. It will thus be seen that as the eccentric it rotates with the shaft 0 the U-shaped portion of the oscillating lever 11 will be oscillated, thereby causing a vibratory motion to the chute (Z.

From the above it will be clearly seen that the connecting devices are extremely simple, yet perfectly capable of performing the functions required of them, that through their use the two machines are so combined that they may be operated singly or jointly, and that in such combination the supporting-frame and main shaft of the feed-cutter are made to perform the same functions for both machines, thereby eifecting a considerable saving in the cost of production of the two machines. 7

Having now described and explained my invention, what I claim as new, and desire to secure by Letters Patent, is I 1.
